If you're not rocking a cart on most of your trips around the local course, you'll appreciate just how much carrying your own clubs can have an effect on your game. The X1R Remote-controlled Caddie ($2000) can carry many things along with your clubs, such as balls, tees, sunglasses, towels, scorecard and pencil holder, amongst others. The cart lasts up to 27 holes on a single charge, so you'll be able to make an entire round of it without worrying about your electric caddie falling behind. Hey, if it's good enough to make GQ's "The 100 best things in the world" list, it's good enough for us.
